HP HP0-Y50 Online Questions & Answers

• Question 1:

  A network architect has collected data on link utilization. When analyzing link utilization, what is the general guideline?

  A. You upgrade a link that is often used at more than 50 percent utilization
  B. You upgrade a link when it reaches 100 percent utilization
  C. You upgrade a link if it sometimes peaks at more than 50 percent utilization
  D. You upgrade a link when it reaches 25 to 30 percent utilization
  A. You upgrade a link that is often used at more than 50 percent utilization

• Question 2:

  HOTSPOT

  A network architect is choosing transceivers for switches-to-switches fiber links. Which factors affect the architect's choice?

  Hot Area:

  

  

• Question 3:

  Refer to the exhibit.

  

  The branch routers have E1 lines into the Frame Relay Service provider network. The exhibit shows just one branch, but the network actually has 30 branches. The HP 6600 Series routers, which are the area border routers (ABRs), have E2

  lines into the Frame Relay network.

  The routers in the exhibit Open Shortest Path First (OSPF). The enable OSPF on network follows:

  In area 2, OSPF is enabled on network 10.2.0.0/16 In area 0, OSPF is enabled on network 10.0.0.0/16

  The customer requires resilience at the WAN core. Which design change best supports that requirement?

  A. Add additional links from the HP 6600 Series routers to the WAN
  B. On each branch router, add a floating static route to one of the ABRs in case the OSPF solution fails
  C. Add a Gigabit link between the HP 6600 Series router with a network in area 0 and area 2.
  D. At each branch, add a redundant link between the switch and the router
  B. On each branch router, add a floating static route to one of the ABRs in case the OSPF solution fails

• Question 4:

  

  When does this design benefit a virtualized data center?

  A. The access layer and core switches use several layers of redundancy protocols, including Multiple Spanning Tree Protocol (MSTP) at Layer 2, Virtual Router Redundancy Procotol (VRRP) at Layer 3, and Intelligent Resilient Framework (IRF) at Layer 4.
  B. The access layer and core switches can connect on link aggregation groups. VLANs can extend across these aggregations, but they are more stable and highly-available than redundant Layer 2 links that use spanning tree.
  C. The access layer switches can integrate their Intelligent Resilient Framework (IRF) capabilities with those on the core switches to create a single CLOS fabric.
  D. The core switches can implement Virtual Ethernet Port Aggregator (VEPA) to extend tunnels for virtualized traffic across the data center backbone.
  B. The access layer and core switches can connect on link aggregation groups. VLANs can extend across these aggregations, but they are more stable and highly-available than redundant Layer 2 links that use spanning tree.

• Question 5:

  A customer has a virtualized data center that uses Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the hosts for the VMs:

  Each host has a network (Hyper-V virtual switch) that supports VM production traffic and own two server 10G NICs

  Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs

  In each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an Intelligent Resilient Framework (IRF) switch.

  Which additional information does the architect need in order to plan the connection to each host?

  A. Whether the virtual switches use Virtual Ethernet Port Aggregate (VEPA) VLAN tagging
  B. Whether the virtual switches use sFlow or NetStream to load balance traffic over the server NICs
  C. Whether the virtual switches support standard Spanning Tree Protocol (STP) or Cisco Per-VLAN Spanning Tree Protocol Plus (PVST+)
  D. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control Protocol[LACP]) and their hashing method
  D. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control Protocol[LACP]) and their hashing method

• Question 9:

  A customer is deploying a mobility solution. The IT staff is not experienced in troubleshooting issues with interference and radio frequency (RF) design, and the customer is worried that the wireless connections will not be stable or will not perform well.

  Which feature of HP unified Wired-WLAN solutions addresses this customer concern?

  A. Hot access controller (AC) backup
  B. Wi-Fi Clear Connect integrated intrusion prevention system (IPS)
  C. Remote-AP capabilities for branch offices
  D. Wi-Fi Clear Connect radio resource management (RRM)
